The '''Low Cost Autonomous Attack System''' (LOCAAS). In 1998 the [[U.S. Air Force]] and [[U.S. Army]] [[Lockheed Martin]] began to examine the feasibility of a small, affordable [[cruise missile]] weapon for use against [[anti-tank weapon|armoured]] and unarmoured vehicles, [[materiel]] and [[personnel]], and if so develop a demonstration program.<ref>[http://www.globalsecurity.org/military/systems/munitions/locaas.htm Low Cost Autonomous Attack System - Global Security]</ref> The program has cost approx. $150,000,000 so far; the cost per unit is calculated to be $30,000 based on a production of 12,000 units.

After being launched from a [[Weapons platform|weapon platform]], it is guided by [[Global Positioning System|GPS]]/[[Inertial navigation system|INS]] to the target general area, where it can [[Loiter (flight)|loiter]]. A [[LIDAR|laser radar]] (LIDAR or LADAR) illuminates the targets, determines their range, and matches their 3-D geometry with pre-loaded signatures. The LOCAAS system then selects the highest priority target and selects the [[Explosively formed penetrator|warhead's mode]] for the best effect.<ref>[http://www.afrlhorizons.com/Briefs/Jun02/MN0205.html Powered Low-Cost Autonomous Attack System - US Air Force Research Laboratory]</ref>

It is part of the Small Bomb System (SBS) program.  The LOCAAS has been cancelled.
